So, I recently inherited a M2.4.4 installation from an “agency”. Long story short, pretty much everything was botched. I managed to fix the file permissions, module conflicts etc and I am now at the point where I want to update to 2.4.5 (to begin with). And here where things go south…
When running a simple composer update, everything breaks and no cli command works anymore, giving the following error:
Interface “MagentoFrameworkObjectManagerResetAfterRequestInterface” not found
I tried removing composer.lock and installing everything using composer install but that gives the same result.
At this point I get the feeling that this “agency” just modified/added/replaced code inside the vendor folder and the composer.json and composer.lock files are just for show.
How do I even begin to fix this? Keep in mind that this is a live site and although I have a staging copy, starting from scratch is not really an option. I know that whatever is in the vendor folder works so is there a way to work backwards from that?
Any help is much appreciated.
